This invention pertains to cablestorage conveyors, and more particularlyto cable conveyors for electric shovels.

In the operation of cutting tools, electric 3 shovels and'the likeinopen'pit mines, it is customary'to furnish power to the tools from asubstation, located near thecenter of distribution from whichthe currentis carried to the tools by aportable' cable or conduit or 1 0 otherdeviceof'suitable design. As the tool proceeds along its working cut, itis of course necessary to provide additional lengths 1 of cable, whichhas heretofore beendone by mounting a reel on the -rear ofthe'tool onF15 which the desired length of conduitwas wound. This, however, is notentirely satisfactory on account of the difficulty of supporting a reelof the necessary capacity because of its size and lack of suitablemounting space, especially with revolving shovels tobe used inconstricted cuts.

It is therefore an objectof this invention to provide a convenient,inexpensive and safe traveling cable supporting carrier which fulfillsall requirements of manufacture and service.

Another object is to provide a conductor carrier'for operating toolswhich enablesthe conductor to be so disposed that the tools maybereadily used and operated to and in restrictedp'oints or cuts.

A further objectisto provide a traveling Figure 2 is a top plan view ofthecable boat with aportibn' of the to eat awayyshowir ig the mountingof the conductor"therein;- and V Figure 3 'is a transverse verticalsection through the cable boatand'top, the same being takensubstantially in the plane as indicated by theline '3-'-3 ofFigure 1.

The cableboat 10, preferably of' steel," consists essentially ofabase-or cable' ca'rrying floor including cross-members '11,'Tpreferablylongitudinally reenforced "by means of runners 12 of any suitable'shapeyshowmas T-bulbs, the same being curved upwardly at their forwardends 13 and curvedslightlyfupwardly attheirafter' ends 14tofi'nsurefeasy sliding of'the boat in operation, Steel sides 15" aresecured to the floor and bracedby spaced transversely' and verticallyextending stanchions 16 extending substantially to the top of saidsides, each of the'sides being pro vided' along "the top edge thereofwith a transversely "projecting roof supporting member 17 The forwardand'after'ends of the "boat arepreferably open or semi-open, the forwardend being provi'ded with a cable guard '18 offany suitable materialadapted to direct the cable to the operating tool.

The fsides "are further -"provided with brackets 19 "secured attheforward end and attached to the tool preferably*by means-of adjustablechain connections 20. Suitable links 'orbrackets 21" may also beprovided on the'sides atselectedpl'aces"'a1ongfthe' length of the boatfor the 1 purpose" of lifting-the boat to facilitate its transportationor manipulation. Hookshapedbrackets 22 may besecured atthe after endofthe sides adjacent the top for'the purpose of engaging the rear edgeof the roof to prevent'the s'a me 'from being detached from theboat,leaving the c'ond-uctor 29'unprotected,

The roof or'top 23 maybe of any construction, suclr as pointed or'ridged'as 'shown-,'the same being overlapping with" respect'to thesides 15and provided with suitably positioned angle members 24 adaptedtocooperate with the members 17to' transversely position said roof. Theroof maybe "of anyply and provided with transverse straps l 25 andlongitudinally'- extending lifting handles "26," said roof beingpreferably finished by forward -and= after -slop'ing pdrtions-28"and-27;

The cable or conductor 29, it is understood, is secured at one end 30 tothe point of energy transmission such as a substation, said cable beingcoiled a suitable number of times within the boat to provide the desiredlength of cable, the tool end 31 of said cable extending through thecable guard and forwardly to the tool.

In operation then, it is only necessary to direct the tool along any outdesired, the tool dragging the boat along with it and the cable payingout of the after end of the boat. It will be seen that this constructionis very satisfactory and is very practical as thecable is completelyguarded both by the sides and the roof which exclude rain and snow aswell as protect any individuals adjacent thereto from coming intocontact with the cable.

It is to be understood that I do not wish to be limited by the exactembodiment of the device shown, which is merely by way of illustrationand not limitation, as various and other forms of the device will ofcourse readily occur to those skilled in the art.

I claim:

1. In a cable boat, the combination of a cable carrying base,,means onsaid base permitting ready movement of said boat in either direction,sides and top for said boat for retaining and protecting said cable, anda guard forsaid cable provided on one end of said boat. i i r 2. In acable boat, the combination of a cable carrying base, spaced meanslongitudinally disposed on said base permitting ready movement of saidboat in either direction, sides and removable cover for partiallyenclosing said boat and retaining the cable, a cable guard provided atthe forward end of said boat to direct the cable to a tool, andcouplingmeans for attaching said boat to said tool.

3. In a cable boat, the combination of a cable carrying base adapted tocarry looped and flatly disposed cable, spaced means longitudinallydisposed on said base permitting ready movement of said boat ineitherdirection, sides and removable cover for partially enclosing saidboat and retaining the cable, the forward and after ends of said'boatbeing open, the cable being adapted to pay off said after end on forwardmovement of said boat, a cable guard provided at the forward end of saidboat to direct the cable to a tool, and coupling means for attachingsaid boat to said tool.
